Title: Method and means for detecting dielectric variations in filamentary material
IPC: G01B7/12
Filed: 1975-02-28
Abstract: 1486503 Capacitance measuring cells EI Du PONT DE NEMOURS & CO 28 Feb 1975 [ 1 March 1974] 8447/75 Heading G1N A capacitance cell for detecting dielectric variations in a moving filamentary material comprises two helicoidal conducting strips arranged coaxially about a path along which the material passes so that an electrical field is distributed in a multiplicity of directions around the material. In order to measure the denier of a yarn 13 the latter is passed through stacked guides 20, 30 and capacitance measuring cell 10, which latter includes a pair of elongate strips co-operating to form a double helix of the same hand and coaxial with the path of yarn 13. The strips are of the same pitch and diameter and are seperated by two spiral slots one of which is left open to provide a string up passage into the cell from the outside and the other of which is filled with insulating material of the same thickness as the strips. Electrical connection to the two plates is via conductor support arms 16, 16'. With the measuring cell as above the effects of thread vibration normal to the axis, and therefore stretch variations in the yarn direction of motion, and also the effects of cross-section shape changes are eliminated. A metallic ground plate 40 may be used. Other arrangements of plates which together produce an effective helical capacitor plate are  described, Figs. 8 to 10 (not shown) whereby a full 360 degrees thread in motion for the yarn is not / necessary but resulting in some loss of compensation. Circuit Fig. 7 The cell 10 is connected in one arm of an A.C. energized bridge 60, the output of which is fed via operational amplifier 70 to a demodulator 72. The demodulator output is fed two processing circuits, the first of which includes a comparator 82 where the signal fed from potentiometer 74 via high pass coupling capacitor 76 is compared with a reference voltage 84 at the non-inverting input of operational amplifier 80 provided with feedback circuit 86 to set the minimum defect length to be detected. When the level of absolute denier detected is such as to exceed the level of 84, pulses are fed from the amplifier 80 via pulse shaper 90 to LED 92 coupled to a photothyristor. The second processing circuit includes operational amplifier 102 connected via high and low pass filter 100 to the demodulator output. A diode bridge 104 is connected in the feedback loop of amplifier 102 and the signal developed across diagonal R gives an average denier variation signal representative of yarn variability for a cut length established by filter 100 and yarn speed; which signal is amplified and averaged for a multiplicity of cut lengths by amplifier 106.

Abstract: 686,325. Couplings for lubricators. TECALEMIT, Ltd. April 4, 1950 [April 14, 1949], No. 8502/50. Class 99 (i) [Also in Group XXXIV] A nozzle 9 of rigid undeformable material or flexible or semi-flexible. material is engaged on the bulbous head 7 of a lubricant nipple G of resilient deformable material having a tapered shank 3 fixed in a supporting member 2. The nozzle may be formed with a longitudinal slot over a part of its length, or alternatively it may comprise a rigid outer portion with a lining of flexible material, and is described as part of a grease gun or the like. In a modification, Fig. 4 (not shown), the resilient nipple shank has a thin external collar and the end of the constricted passage 6 adjacent the member 2 opens through the apex of a conical portion formed in the resilient material. Thus, upon cessation of lubricating pressure from the grease gun, the back pressure of the lubricant seals the said constricted portion. In a further modification, a nipple is formed of a resilient portion secured to a rigid portion; the rigid portion may be screwthreaded and have the resilient portion secured thereto at an angle of 45 degrees, and may include in the lubricant passage a metallic tube with a spring-urged non-return valve to prevent the escape of lubricant. The resilient material from which the nipple is made may be natural or synthetic rubber, polyvinyl chloride, &c. and may be strengthened by cotton, spun glass or spun metal wires and the like.

The twist inserted in a yarn e.g. the false twist inserted in a crimping process, is prevented from running back to the supply means by a twist stopper comprising spaced apart walls. In Fig. 3 the yarn is passed between the opposed surfaces 23, 23<SP>1</SP> of a slot the depth of which is at least twice the diameter of the filaments in the yarn. In Fig. 4, not shown, the surfaces are formed in a closed curved channel of rectangular cross section. In Fig. 6, not shown the surfaces are formed by spaced parallel rods (43, 43<SP>1</SP>) e.g. of synthetic sapphire. Two such arrangements may be provided in series along the yarn. In Fig. 8 the surfaces are formed on annular recesses 53, 53<SP>1</SP> in a pair of rotating rollers. The recessed portions may be provided at one end of the roller pair to facilitate threading up. The surfaces may be movable relative to each other and be provided with micrometer means to adjust the separation thereof. In Fig. 3 one of the surfaces may be stepped so that paths with different wall separation are provided. The surfaces may be movable apart to facilitate threading. The entrance and exit to the opposed walls are preferably tapering. In Fig. 9, not shown, the twist stopper is formed by a hole (25) in a plate. A series of holes of varying diameters is provided for different yarns. Elliptical or polygonal holes may be provided. In Fig. 11, not shown, the twist stopper is formed by a tube (61) preferably having belled ends. In use with false twist crimping apparatus the twist stopper may be flared in the heating zone.

Abstract: 435,364. Regulating gas-compressors. SULZER FRERES SOC. ANON., Winterthur, Switzerland. March 21, 1935, No. 8924. Convention date, April 6, 1934. [Class 8 (i)] [See also Group XXVI] In a compressor of the type in which pistons 5, 8, reciprocating oppositely in an internal-combustion cylinder 2 carry the pistons 7, 9 of compressor cylinders 3, 4, excessive outward movement of the pistons is prevented by limiting the maximum delivery of the fuel-injection pump of the cylinder 2 in accordance with the pressure in the discharge pipe 17 of the compressors 3, 4, or the pressure in the exhaust pipe of the cylinder 2. The outer ends of the cylinders 3, 4, deliver air to the pipe 17, while the inner ends supply scavenging air to the ports 10 of the cylinder 2. The discharge of the fuel-injection pump 20, Fig. 2, is controlled by means of a spill valve 25, which is opened by a projection 26 on a lever 27. The latter is operated by a link from a lever 29 which carries a roller interposed between the operating cam and the pump plunger. The lever 27 is pivoted on an eccentric 31 on a spindle 30, which can be adjusted by the governor 33 through a lever 32, link 34 and a cylinder 35, containing a piston 36 moving against the action of a spring 37. The outward movement of the lever 32 is limited by a stop 38 formed by one arm of a lever, the other arm of which is operated by a piston 40, exposed through a pipe 19 to the pressure in the discharge pipe 17.
